Furthermore, beingadapted to operate as an aid to the refrigerat-ing-nmchi-nc in the.

summer montns,it will be possible to get along with less powerful refrigeratingmachines where they are combined with suchan icechamber.

z 5 The air-shaft L opens into the atmosphere,

and is connected with the fan H through thebox D in. this instance. ;It is provided in order that in cold weather fresh air may be drawn from the exterior of the building and 0 blown into it to displace the contaminated air in it, which may be let out through the doors and windows. During the warmer seasons this air-shaft must be tightly closed-and made non-conducting where it .joins the box D.

the fermenting-tubs in alfermenting'room ofa brewery, we draw off continually the carbonic acid and other .gases and fungi of fermentation always hovering above the fermenting o wort in the tubs, retarding andfdebasing the fermentation.- These impurities so drawn off are absorbed, if not all, in greater part at least, by the water of condensation formed on the .refrigeratingpipcs,,for, in practice, we find that the air in the building cooled by ourap- .paratns is kept remarkably pure. Inj'consequence a'bette'r fermentation resulted, and

the flow of the refrigerant to attain the first,

object of our invention, making the travel'of the air and refrigerant sufiiciently extended so that the greater portion of the moisture in the air might be -condenscd'as watcr'onthe warmer ends of the refrigerating-pipes.

Instead of jacketed refrigerating-pipes ep- 6 5 crating as described, the air may be cooled by refrigerating-pipes through which a continu- By drawing the air from above the tops of one flow of a non-congealable liquid 'is maintained by a pump from a reservoir wherein said non-congealable liquid is cooled by direct contact with a coil or coils of ammonia or other refrigerating-pipes, the non-congealable liquid being caused to flow through the pipes in a direction opposite to the travel of the air, as before but we" prefer the construction first described, for itis both simple and efi'ective in operation.

-.In so|nc=.cases we propose to pass the 'air along the refrigerating-pipesin aspiral or zig- "zag direction, so that the travel of the air would considerably exceed the travel of the refrigerant. ,=Snch modification we consider'as a variation of our invention and as covered by our claims. f w

Weare aware that it is common to cool 'liqui'ds'by passing them alongcooling or re; frigeratin g pipes in 'a direction opposite to the flow of the refrigerant, the travel'of the liquid to be cooled being substantially (to-extensive .with the travel of the refrigerant; but the cooling of liquids does not involve'injnrious accumulation of frost on the refrigeratingpipes, whichvis, on the other hand, avery serious difficulty met with in the cooling of air by refrigerating-pipes. Hence our described method of cooling air is not analogous to the cooling of liquids in the same way, because by preventinginjurious accui'nulation of frost on the refrigerating-pipes it produces a new resnlt,and one of great importance to a continuous effectivecooling of air.

We are also aware that it is common to cool air by blowing it through an ice chamber or box'; but so. far as we know we are the first to combine refrigeratiiig;1ii1)es forthe artificial cooling of air with an ice-box for also cooling the air by the natural cold of the ice therein.

\Vhat we claim as 'our invention, and desire I to secure by Letters Patent, is-

1. In cooling-curren ts of air by refrigerating pipes or tubes, the method of preventing in; j nrious accumulation of frost on the said pipes, which method consists of forcing the.

.air through a suitable box along the refrigerating-pipes in a direction'opposite to the flow of the refrigerantthrough said pipes, the travel of the air being substantiallyeo-cxten sive with the travel of the refrigerant, substantially as before set forth. '2. The combination, substantially as before set forth, of the air-box, the refrigerating-pipes the inlet of the box, and being thus substantially of equal lengththerewith, and the fan or blower forcing the air along the said pipes in a direction opposite to the flow of the re-, frigerant.
